Figure 3

Effect of L-carnitine on the activities and protein expressions of SOD and CAT in H 2 O 2 -damaged HL7702 cells. Cells were treated with L-carnitine for 12 h and followed by the treatment of H2O2 (300 μM) for 12 h. A: Total SOD and CAT activities were calculated in units of activity per mg of total protein. B: Cu,Zn-SOD and CAT expressions were determined by western blot analysis. Results were expressed as the ratio of expression level of Cu,Zn-SOD or CAT over β-actin. Each value represents the mean of three replicates. #P < 0.01 vs. control; *P < 0.05, **P < 0.01 vs. H2O2 alone.
